Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Corn starch
Thickens the milk mixture into a smooth, sliceable custard as it heats.
Eggs
Add richness and help set the filling once it is combined with the hot mixture.
Cocoa
Provides the chocolate flavour and deep colour of the filling.
Milk
Forms the liquid base that the starch thickens into the custard.
Sugar
Sweetens the filling and balances the bitterness of the cocoa.

The step that matters

Stir in the beaten eggs and vanilla extract. Add the eggs off the heat after the filling has thickened, so they blend in smoothly without scrambling. Stir steadily while adding them.

Swap the walnut

How well each one fits the dish's main ingredients (cocoa, milk, sugar, butter, corn, egg, vanilla):

  1. Almondfits better
  2. Pecansfits about as well
  3. Walnutthe original
  4. Nutsfits about as well

Fit is the average pairing score against cocoa, milk, sugar, butter, corn, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
